Foreword
ISO (the International Organization for Standardization) is a worldwide federation of national standards
bodies (ISO member bodies). The work of preparing International Standards is normally carried out through
ISO technical committees. Each member body interested in a subject for which a technical committee
has been established has the right to be represented on that committee. International organizations,
governmental and non-governmental, in liaison with ISO, also take part in the work. ISO collaborates closely
with the International Electrotechnical Commission (IEC) on all matters of electrotechnical standardization.
The procedures used to develop this document and those intended for its further maintenance are described
in the ISO/IEC Directives, Part 1. In particular, the different approval criteria needed for the different types
of ISO document should be noted. This document was drafted in accordance with the editorial rules of the
ISO/IEC Directives, Part 2 (see www.iso.org/directives).
ISO draws attention to the possibility that the implementation of this document may involve the use of (a)
patent(s). ISO takes no position concerning the evidence, validity or applicability of any claimed patent
rights in respect thereof. As of the date of publication of this document, ISO had not received notice of (a)
patent(s) which may be required to implement this document. However, implementers are cautioned that
this may not represent the latest information, which may be obtained from the patent database available at
www.iso.org/patents. ISO shall not be held responsible for identifying any or all such patent rights.
Any trade name used in this document is information given for the convenience of users and does not
constitute an endorsement.
For an explanation of the voluntary nature of standards, the meaning of ISO specific terms and expressions
related to conformity assessment, as well as information about ISO's adherence to the World Trade
Organization (WTO) principles in the Technical Barriers to Trade (TBT), see www.iso.org/iso/foreword.html.
This document was prepared by Technical Committee ISO/TC 67, Oil and gas industries including lower
carbon energy, Subcommittee SC 3, Drilling and completion fluids, well cements and treatment fluids, in
collaboration with the European Committee for Standardization (CEN) Technical Committee CEN/TC 12, Oil
and gas industries including lower carbon energy, in accordance with the Agreement on technical cooperation
between ISO and CEN (Vienna Agreement).
This second edition cancels and replaces the first edition (ISO 13503-2:2006), which has been technically
revised. It also incorporates the Amendment ISO 13503-2:2006/Amd 1:2009.
This document supplements API Std 19C, 2nd edition (2018).
The technical requirements of this document and API Std 19C used to be identical. In the meantime API
Std 19C has been technically revised as API Std 19C, 2nd edition (2018). The purpose of this edition
of ISO 13503-2 is to bring it up to date, by referencing the current edition of API Std 19C and including
supplementary content.
The main changes are as follows:
— a new stand sampling device has been used for proppant packed in bags;
— proppant on the sieves has been removed and directly weighed in sieve analysis testing;
— the average diameter calculation has been added;
— the remaining total amount on the last sieve and in the pan has been updated to not exceed 2 % by mass
of the total tested proppant sample;
— PropPaver loading device has been used instead of Pluviator loading device;
— the upper and lower designating sieve sizes have been kept for sample prep
